Subject: avoid $status and $options in POSIX mode
Date: Fri, 17 Sep 2010 11:33:08 -0600 [thread overview]
Message-ID: <4C93A654.90807@redhat.com> (raw)
POSIX states "The name space of environment variable names containing
lowercase letters is reserved for applications. Applications can define
any environment variables with names from this name space without
modifying the behavior of the standard utilities."
http://www.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html#tag_08
Yet, the existence of zsh-magic variables like $status and $options
infringe upon the right of a user's script to use this namespace for
their own desires. For example, see this recent autoconf patch:
http://git.sv.gnu.org/cgit/autoconf.git/commit/?id=23a2c336
It would be really nice if 'emulate sh' could disable zsh magic handling
of any variables that infringe upon the lower-case namespace reserved
for applications.
